CLAMP.

SPECIFICATION forming part of Letters Patent No. 555,614, dated March 3,1896.

Application filed April 2'7, 1895. $erial No. 547,398. (No model.)

To all whom it may concern.-

Be it known that I, JAMES MOWRER, a citizen of the United States,residing at Casper, in the county of Natrona and State of Wyoming, haveinvented certain new and useful Improvements in Clamps; and I do declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvement-s in that class of clamps whichcomprise two loops and are provided with screws for clamping articles insaid loops, and its novelty will be fully understood from the followingdescription and claim when taken in conjunction with the annexeddrawings, in which Figure 1 is a View illustrating the manner of usingmy improved clamp; and Fig. 2 is an enlarged transverse section taken inthe plane indicated by the line 00 00 of Fig. 1, looking in thedirection of the arrow.

Referring by letter to said drawings, A A indicate the sections of awindow-frame.

B indicates a square, and 0 indicates my improved clamps, of which twoare preferably employed in conjunction. The body D of these clamps O- iscast in one piece and has all of its parts resting in the same plane, asshown, so that a plurality of the clamps will take up but a minimumamount of room when not in "use. The said body D comprises the largeloop or elbow a, which is designed to straddle a frame-section, and thesmaller loop b, which-rests approximately at right angles to the loop aand in the same plane therewith, and is designed to straddle the squareso as to hold the same against the frame-section, as illustrated. At oradjacent to its ends the body D is provided with threaded apertures orbores c d, which are disposed at right angles to each other and aredesigned to receive the binding-screws E F, which in turn are designedand adapted to engage the frame-sec tion and square, respectively, asbetter illustrated in Fig. 2.

In order to prevent the binding-screw F from scratching, indenting, orotherwise marring the square, I provide the bearing-plate G, which isconnected to the inner side of the loop Z), as shown, and is designed torest between the screw F and the square and receive the impingement ofsaid screw.

The manner of using my improved clamps is illustrated in Fig. 1, and isas follows: The clamps O are first connected to the blade and tongue ofthe square B, as illustrated, and the clamps are then adjusted so thatthe loops a will straddle the frame-sections and the blade and tongue ofthe square will rest against the inner sides of the sections and atright angles thereto. The screws E are then tightened, so as to draw thesquare tightly against the frame-sections, when said sections will beheld in a perfectly-square position for the purpose before stated.

When it is desired to remove the clamps from the frame-sections and thesquare, it is simply necessary to loosen the screws E, so that theclamps and the square may be disconnected from the frame-sections andthe screws F, so that the clamps may be disconnected from the square. Asbetter illustrated in Fig. 2, the loops a b are arranged at right anglesto each other and in the same plane, and so that the mouth of the loop arests at the side of the mouth of loop I) and opposite the threaded bore0, which receives the screw E. This permits of the square resting atright angles to the frame-sections and also enables a single screw E, bybinding a frame-section against the edge of the square, to securely holdthe frame-section in position and in proper relation to the square.

The threaded bores c and cl are arranged in the same plane as the bodyportion D of the clamp, as are also the screws E F, and in consequenceof this and the fact that all the parts of the said body are in the sameplane, as before stated, it will be seen that a number of the clampswhen not in use may be placed in a very small space and that they may bevery easily handled.

It will be seen from the foregoing description, taken in connection withthe drawings, that my improved clamps are exceedingly cheap and simple;that they may be readily applied, and that they will serve effectuallyto hold the sections of a Window-frame perfectly square, which is animportant desideratuln.

Having described my invention, what I claim is The clamp describedconsisting essentially of the body portion D, formed in one piece withall its parts in the same plane and having the threaded apertures orbores a, (Z, adjacent to its ends; said apertures or bores beingdisposed in the same plane as the body and at right angles to eachother, and also havin g the loops a, b, resting at right angles to eachother and in the same plane and so that the mouth of the loop 1), willbe at the side of the mouth of the loop a, and communicate therewith,and
